"Great Walls" examines the politics of walls by using the Great Wall of China to rethink both current border walls (the Trump Wall, the West Bank Barrier) and iconic walls (the Berlin Wall). It examines how walls serve as sites of ideology, both Cold War ideology and anti-immigrant ideology. It also examines how walls are sites of experience in every life by juxtaposing archive clips of political leaders and ethnographic film of ordinary people. The film utilizes walls to ask how personal experiences shape ideology and vice versa.
